Quick start
You will need:
- Ubuntu 20.04
- Assembled DuPAL 2.0 w/ 20 pin ZIF installed
- ATMEGA328P blank / in any state
- DuPAL power supply and USB serial
- avrdude compatible programmer
- I used avrispmkII
- PAL16L8
- Optional: tool to flash PAL16L8
- TL866 won't work :(
Quick flash
For more information see the main page
Pre-compiled hex files: https://proghq.org/media/dupal/
sudo apt-get install -y avrdude
ISP connection:
* Pin 1 (red stripe in cable) towards crystal * Notch faces towards ATMEGA
You need an avrdude compatible programmer. To see the list of compatible programmers type
avrdude -c help
Once you know the flag you need, here's an example assuming avrispmkII:
avrdude -v -c avrispmkII -P usb -p atmega328p -e -u \ -U efuse:w:0xFD:m \ -U hfuse:w:0xDE:m \ -U lfuse:w:0xFF:m \ -U flash:w:optiboot_atmega328.hex
You should see a green blinky LED
avrdude -v -c avrispmkII -P usb -p atmega328p -u -D \ -U flash:w:dupal_v0.1.2.hex
The green blinky might stop. Hit the reset button and it should blink again
Start up a serial port at 57600 (ex: screen /dev/ttyUSB0 115200). Hit "reset" and you should see:
(blinky for a few seconds)
Then:
DuPAL - 0.1.2 REMOTE_CONTROL_ENABLED
If you see this, congrats! your DuPAL is flashed and ready to go
A healthy board should have a steady red power LED and a brief green blink at power on
Quick test
For more information see the main page

Optiboot
# https://github.com/Optiboot/optiboot # 328P uses 115200? # a few use 57600 but not the one we need :( # wget https://github.com/Optiboot/optiboot/releases/download/v8.0/Optiboot-8.0.zip git clone https://github.com/Optiboot/optiboot.git cd optiboot git checkout -b v8.0 v8.0 cd bootloaders/optiboot make atmega328 AVR_FREQ=20000000L LED_START_FLASHES=8 BAUD_RATE=57600 # sha1sum optiboot_atmega328.hex # 8a16ce8d98d7bf002c54c7aa911bfd124d9e1961 optiboot_atmega328.hex
Flash optiboot. Example CLI to use ISP header, but can also put into tl866 etc
Sample command line:
Originally I tried using BP Microsystems but didn't work (fuses not set right?). I then flashed using avrdude / header and worked (green LED blinking).
TODO: dump end flash so can program using bp
cd DuPAL_Firmware make make program
